Safety Precautions



Warning!

Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections
while the power is on. Sensitive electronic components can be
damaged by sudden power surges. Only experienced electronic
personnel should open the PC chassis.



Caution!

Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all electronic components
in a static-dissipative surface or static-shielded bag when they are
not in the chassis.

Chapter 2 Installations

2.1 Memory Module（（（（DIMM））））Installation

IA31 motherboard supports one 200-pin SODIMM slot. The socket supports up to

2GB DDR2 400/533 SDRAM.

Step.2. Press downwards on SODIMM until the retaining clips at both ends fully snap

back in place and the SODIMM is properly seated.



Caution

!

The SODIMM only fits in one correct orientation. It will cause

permanent damage to the development board and the SODIMM if

the SODIMM is forced into the slot at the incorrect orientation.

2.2 I/O Equipment Installation

2.2.1 12V DC-IN

The Motherboard allows plugging 12V DC-IN jack on the board without another

power module converter under powered consumption by Intel Atom N270 1.6GHz

processor.

2.2.2 PS/2 Keyboard and PS/2 Mouse

The Motherboard provides one PS/2 interface. The PS/2 connector supports Keyboard

and Mouse.

2.2.3 Serial COM ports

Four RS-232 connectors build in the rear I/O. Fourth optional COM ports support

RS-232. When an optional touch-screen is ordered with PPC, serial com port can

connect to a serial or an optional touch-screen. One optional COM port supports

RS232/422/485 choice through jumper setting.

2.2.4 External VGA

The Motherboard has one VGA port that can be connected to an external CRT/ LCD

monitor. Use VGA cable to connect to an external CRT / LCD monitor, and connect

the power cable to the outlet. The VGA connector is a standard 15-pin D-SUB

connector.

2.2.5 Ethernet interface

The Motherboard is equipped with Realtek RTL8111B chipsets which is fully

compliant with the 10/100/1000 Mbps Ethernet protocol compatible. It is supported

by major network operating systems. The Ethernet ports provide two standard RJ-45

jacks.

2.2.6 USB ports

Four USB devices (Two with pin headers) may be connected to the system though an

adapter cable. Various adapters may come with USB ports. USB usually connect the

external system to the system. The USB ports support hot plug-in connection.

Whatever, you should install the device driver before you use the device.

2.2.7 Audio Jack ( Pin-header)

The Audio 5.1 channel capabilities are provided by a Realtek ALC655 chipset

supporting digital audio outputs. The audio interface includes Mic-in,: line-in and

line-out.

2.4 Jumper Setting

A pair of needle-nose pliers may be helpful when working with jumpers. If you have

any doubts about the best hardware configuration for your application, contact your

local distributor or sales representative before you make any changes. Generally, you

simply need a standard cable to make most connections.

The jumper setting diagram is as below. If a jumper shorts pin 1 and pin 2, the setting

diagram is shown as the right one.

The following tables list the function of each of the board's jumpers.
